Application filed May 6,

To all whom it may concern:

Be it known that I, CHARLIE L. HALL, citizen of the United States,residing at Bryan, in the county of Brazos and State of Texas, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a specification.

This invention has relation to plows.

The object of the invention is to provide an adjustable slide mechanismwhich may be moved up or down on the standard to offset the movement ofthe sweep or shovel or plow point when the standard is adjusted forsteep or sloping furrows and which is adapted to be adjusted in parallelrelation to the plow beam.

Another feature resides in an adjustable standard connected with theslide mechanism and by which the slide mechanism is adjusted and wherebythe slide mechanism can be adjusted with relation to the plow beamirrespective of the vertical adjustment.

A still further object lies in adjustable handles arranged to be swungup or down and to either side to compensate for the adjustment of thestandards and the slide mechanism; together with a rudder carried by theslide mechanism.

Finally the object of the invention is to provide means of the characterdescribed that will be strong, durable, efficient, and easy ofoperation, simple and comparatively inexpensive to construct, and alsoin which the several parts will not be likely to get out of workingorder.

Vith the above and other objects in view, the invention has relation tocertain novel features of construction and operation, an example ofwhich is described in this specitication and illustrated in theaccompanying drawings, wherein:

I is a detail of the flange links and adjacent parts, Fig. 11, is a planview of the slide 1 shoes, Fig. 12, is a detail of the rudder blade, 1and Fig. 13, is a detail in plan showing the manner of attaching wingbraces.

t In the drawings the numeral 1, designates a metal plow beam having anintegral stock 2 and a rear segmental portion 3 which is connected atits rear end with the lower rear side of the segment by a brace 41.These parts are preferably a single casting with suitable bosses atproper points.

Near the lower end of the brace and just in rear of the stock, handles 5are pivoted on each side of the brace upon a bolt 6 passingtherethrough. These handles extend at an angle past the segment 3. Inthe segment, a curved slot 7 having its radius from the center of thebolt 6, receives a transversely curved rod 8 suitably fastened at eachend at one of the handles. This rod has a continuous screw threadengaged by nuts 9, one binding on each. side of the segment. It isapparent that the slot 7 permits the handles to be swung vertically orraised or lowered to suit the height of the plowman. By reason of thenuts 9 the handles may be adjusted toward either side by rotating thenuts either to the right or left on the rod which feeds the rod throughthe slot. The handles are fastened in position by turning the nut-s sothat they bind against the segment.

On each side of the stock 2, a standard member 10 is disposed. A pivotbolt 11 is carried in the lower end of the stock and at the intersectionof the stock and the beam, a slot 12 is provided and curved in the arcof a circle having its center coincident with the bolt 11. The members10 are pivoted near their central portion on the bolt 11 and areconnected at their upper ends by a bolt 13 passing through the slot 12.The lower ends of the members may thus be swung by moving the bolt 13.in the slot and fastened in position by fastening the said bolt. Eachmember at its lower portion is provided with a series of holes 11arranged one above the other and adapted to receive transverse bolts 15.

A pair of flange links 16 are disposed against the lower ends of themembers 10. As shown in Figs. 4c and 5, each link is provided with alongitudinal flange 17 which is offset. Each flange has a longitudinalslot 18 through which the bolts are passed transversely. By provision ofthe slots, the flanges which fit between the members 10, may be slidvertically on the standard. The links 16 may be inverted or placedagainst the front sides of the standard members 10 as shown in Figs. 1and 41 or against the rear sides as shown in Figs. 5 and 9.

In Fig. 7 a detail of one of the frogs 1.9 is

'used in connection with the links and standard members. The frog issuitably formed and is adapted to have landsides, shares and mold-boardsbolted thereto. On its rear side the frog is formed with vertical webs20 which are disposed to lie in contact with the edges of the links asshown in Fig. 4:, or the edges of the members 10 as shown in Fig. 5. Anintegral stem 21 extends from the rear side of the frog and near itsintersection with the frog has a rectangular boss 22 adapted to fitsnugly between the links 16 as shown in Fig. 4: or between the standardmembers 10 as shown in Fig. 5. The rear end of the stem is screwthreaded and adapted to receive a nut 23 by which the frog is fastenedin place. It is to be understood that various shapes and styles of frogsmay be used.

Fastened between the lower end of the flange links by a transverse bolt24, are a pair of slide shoes 25 recessed at 26 as shown in Fig. 11 toreceive a longitudinal guide blade or rudder 27. As shown in Figs. 10and 12, the blade 27 has a slot 28 at an angle forward and whichreceives the bolt 24 between the shoes and whereby the blade may beadjusted vertically to Vary its projection below the shoes. By means ofthis guide blade the plow is held to its course and lateral displacementreduced to a minimum. The guide blade terminates a short distance infront of opposed ears 29, one projecting up from each shoe. To the outerside of each ear the lower end of a link 30 is pivoted on a bolt 31passing transversely through the parts as shown in Fig. 11. These linksare pivoted at their upper ends on each side of the rear end of aforwardly extending connecting bar 32. A bolt 33 is passed transverselythrough the links 30 and the bar 32; while at its forward end, the baris pivoted between the upper ends of the links 16 on a transverse bolt34. It will. be noted that the distance between thecenters of the bolts24 and 31 is greater than the distance between the centers of the bolts33 and 34. This arrangement constitutes an adjustable frame or slidemechanism and the particular object is to adjust the shoes parallel tothe beam after the standard members 10 have been adjusted as indicatedin full and dotted lines in Fig. 9.

WVhile in most instances the flange links 16 can be placed in rear ofthe members 10 with the flanges 17 directed forward between the members10 as shown in Figs. 5 and 9, it is necessary to reverse the links asshown in Figs. 1 and 4 when the standard is adjusted as shown in Fig. 9to permit the connecting bar 32 to swing down. When the links 16 aredisposed as shown in Figs. 1 and 5, the frog 19 may be fastened closerto the standard members.

For bracing wings and molds, a short link 35 is pivoted on the bolt 31.In Fig. 13 the link is shown in dotted lines swung forward and the endof a single brace 36 fastened thereto; while in full lines the link isshown swung rearward to receive opposed braces 37. This figure alsoillustrates the disposition of the landside 38 as parallel with andalong one side of the shoes 25. In other figures the l'andside isomitted for the sake of clearness.
